ANOVA 3-Way

Click to go to the Apple Mac App Store.

Click to go to the Microsoft Windows Store.

This app will compute an Analysis of Variance, three-way classification. Example datasets are included to help users get started quickly. These examples serve as guides for organizing and entering data. You can turn these examples off under Preferences. A main menu provides the organizational structure for this app. From this menu you can choose to start a new project, work on an existing project (such as data entry), or produce tables and graphs for a project. Menu items can also be reached from buttons on the toolbar.

Each new ANOVA is organized as a project. This organizational structure follows throughout all of the regression and ANOVA apps in the Computational Suite. New projects are created by assigning a unique ID to the project. After entering the ID you can enter details associated with the project along with data. Data can be entered manually or from a comma delimited text file.

Reports include the ANOVA table and significance. If you have made any data entry errors, simply go back and correct them, then click on the reports menu item again. Reports can also be sent to a text file if you need to insert them into a word processing document such as Apple Pages or MS Word.

Both 2D and 3D graphics are available. For the 3D graph, use the Zoom, Yaw, Pitch and Roll controls to see the entire graph from different angles.

This app is also equipped with an automatic backup system. Each time you quit the app a backup copy is generated. Up to 100 backup copies are kept. To restore a project from a prior backup, select the last menu item and follow the instructions.
